Pier 22a #1 (API 42-317-36864) is a plugged well in Martin County, plugged March 21, 2024, last operated by Diamondback E&P LLC.

The RRC has issued 2 drilling permits between 2011 and 2017, permitted to 12,000 ft.

It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Strawn, Atoka.

Its lease has reported 74.2K barrels of oil and 143K mcf of gas since September 2011, last reporting volume in November 2025. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Wells named Pier 22A

Diamondback E&P LLC's other wells filed under this lease name in Martin County, newest permit first. The RRC gives a gas well its own lease number, so the name is what joins the wells of a unit.

Chain of custody

Operator on the lease's P-4

Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.

These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.
